Make settings for the time between notifications about insufficient resources at the station. Because now this notification appears as soon as the old one has passed.

As I remember, this was in the first versions of the game, and had this name in the mod settings:
Message filter timeout (ticks)

Is this just for the resources?

You can also turn off the warnings on a per-station basis.

The old code used a quite involved mechanism to rate-limit the messages. Removing it and replacing it with the "do not repeat as long as message is visible" setting from the core game made this much simpler and also more UPS friendly.

Can you tell me where this option is to disable it on a per-station basis?
I have selected in the settings: Message level: Errors & Warnings turned on

I'm just playing PY right now and when the production rates are sometimes 0.5 per second, it takes up to 20 minutes to accumulate enough for a full train. Notifications are driving me crazy)

If you use the LTN Combinator click the bottom right checkbox (Disable Warning Messages). If you use just regular combinators, send the "Disable Warning Messages" signal

oh, thanks, that helps
